skos:definition "<b>!</b> This usage is specific to the Transport Regulations, and should otherwise be <br/>
avoided.<br/>
A solid object which is not itself 'radioactive' but which has 'radioactive '<br/>
'material' distributed on its surfaces. 'SCOs' shall be in one of two groups:<br/>
(a)<br/>
<i><b>SCO-I.</b></i> A solid object on which:<br/>
(i) The 'non-fixed contamination' on the accessible surface averaged over <br/>
300 cm2 (or the area of the surface if less than 300 cm2) does not <br/>exceed 4 Bq/cm2 for beta and gamma emitters and <i>low toxicity alpha <br/>emitters</i>, or 0.4 Bq/cm2 for all other alpha emitters; and<br/>
(ii) The 'fixed contamination' on the accessible surface averaged over <br/>
300 cm2 (or the area of the surface if less than 300 cm2) does not <br/>exceed 4 × 104 Bq/cm2 for beta and gamma emitters and <i>low toxicity <br/>alpha emitters</i>, or 4 × 103 Bq/cm2 for all other alpha emitters; and<br/>
(iii) The 'non-fixed contamination' plus the 'fixed contamination' on the <br/>
inaccessible surface averaged over 300 cm2 (or the area of the surface <br/>if less than 300 cm2) does not exceed 4 × 104 Bq/cm2 for beta and <br/>
gamma emitters and 'low toxicity alpha emitters', or 4 × 103 Bq/cm2 for <br/>all other alpha emitters.<br/>
(b)<br/>
<i><b>SCO-II.</b></i> A solid object on which either the 'fixed' or <i>non-fixed <br/>contamination</i> on the surface exceeds the applicable 'limits' specified for <br/>'SCO-I' in (a) above and on which:<br/>
(i) The 'non-fixed contamination' on the accessible surface averaged over <br/>
300 cm2 (or the area of the surface if less than 300 cm2) does not <br/>exceed 400 Bq/cm2 for beta and gamma emitters and <i>low toxicity <br/>alpha emitters</i>, or 40 Bq/cm2 for all other alpha emitters; and<br/>
(ii) The 'fixed contamination' on the accessible surface, averaged over <br/>
300 cm2 (or the area of the surface if less than 300 cm2) does not <br/>exceed 8 × 105 Bq/cm2 for beta and gamma emitters and <i>low toxicity <br/>alpha emitters</i>, or 8 × 104 Bq/cm2 for all other alpha emitters; and<br/>
(iii) The 'non-fixed contamination' plus the 'fixed contamination' on the <br/>
inaccessible surface averaged over 300 cm2 (or the area of the surface <br/>if less than 300 cm2) does not exceed 8 × 105 Bq/cm2 for beta and <br/>gamma emitters and 'low toxicity alpha emitters', or 8 × 104 Bq/cm2 for <br/>all other alpha emitters. (From Ref. [2].)<br/>" (en)
